Analyze firmware, software protections, operating system internals, and wireless protocols to uncover exploitable security flaws
Conduct reverse engineering and vulnerability research against complex Linux-based and embedded systems
Utilize and extend custom tools to analyze and manipulate software/firmware binaries
Develop capabilities that leverage novel telecommunications access mechanisms
Collaborate closely with developers, vulnerability researchers, and hardware engineers in a fast-paced environment
Solve complex, ambiguous technical challenges with limited prior experience
Engage in technical discussions with transition partners and mission stakeholders

Firmware analysis (ARM, RTOS, or similar)
Fuzzing and exploit development
Wireless protocols through Wireshark
File system forensics and fault injection frameworks
Scripting with Binary Ninja or Ghidra
Binary Ninja API or Ghidra
Active U.S. Top Secret security clearance with ability to obtain and maintain SCI access
Nice to Have (Preferred Qualifications):
